BUTT-BOARD FOR GRAIN-BINDERS.

SPECIFICATION forming part of Lettersy Patent No. 473,559, dated April 26, 1892. Application filed April 3, 1891. Serial No. 387,574. (No model.)

To all whom, t may concern:

Be it known that I, GEORGE SCHUBERT, a citizen of the United States, residing at Walnut, in the county of Bosque and State of Texas, have invented certain new and useful adjust said gavelin regard to length so that' short grain will be bound near the center as Well as long grain, and said adjustment is so arranged that it can be changed by the operator whenever so desired. Said butt-board and mechanism are especially adapted for the conveyer invented by myself and patented February 17, 1891, No. 446,473. It has refer- Vence more especially to the construction of the butt-'board and operating parts, so as to even the butts of the grain and adjust the same to proper position to the binder at one single movement of the butt-board, and to construct such operating parts so that the operator can increase or decrease the movement of the butt-board Without checking the 1n0vement of the machine, and thus adjust the gavel of grain so that a long gavel or a short gavel will be bound nearer the center of its length Without any shifting of the binder mechanism. I attain these objects by the mechanism illustrated in the accompanying` drawings, in Which- Figure l is a plan View of a harvestenplatform provided with my improvements, the upper plate of the platform being mostly removed, so as to show the construction of the lever arrangement below said plate. Fig. 2 is a front view of the inner portion of Fig. l with the linger-bar removed, so as to show parts beyond in full lines. Fig. 3 is a vertical cross-section on line l 1, Fig. l, showing the parts beyond the section-line in full lines. Fig. 4. is a plan view of part of the machine shown in Fig. l, with the upper plate of the platform removed, with the shiftable lever moved to the rear, moving the grainward end of the butt-board only and only far enough to bring said butt-board parallel with the front edge of the platform, as shown in said figure. Fig. 5 is a detail View of one of the operatinglevers.

l Referring to the drawings, A designates the platform, constructed of plates a and a', braced apart by strips b and b', to which the plates a and a arelsecured. The strips b and bv form the usual walls for the passage-way for the conveyor C, a slot A being left between the plates c. for the conveyer C. The strip b is cut down at P to permit the Working of the arm l?2 of lever P. The front edge of the lower plate a is secured to the lower" flange of the finger-bar B, and the front upper plate a is secured to the upper flange of the flnger-barB. The inner ends of the upper plates a are slightly elevated. The front edge of said elevated portion of front plate a is turned down, forming the part a2, and then inward, forming the flange d3, by Which said elevated part of the frontplate d is secured to the )upper flange of the finger-bar. (See Fig. 3.

A2 designates the grain-board, secured to the plates a and a by corner-irons A3 A3. (Seen in Fig. l.) The finger-bar Bis provided with the usual guard-fingers B and a shoe B2. To said shoe B2 can be secured an inner grain-board d. A slot is made in the front a2 of plate ct for the operation of lever g, and a notch t is made in the front plate a for the operation of the stud f2, and the front plate a. is perforated at o for thepurpose hereinafter described.

E designates a shaft located near the inner end of the platform A, With its front bearing C secured to the linger-bar B and extending through the strip l), with its rear bearing in the strip b. Said shaft is provided with a pinion F on its forward projecting end and a sprocket-Wheel e, located in the slot A', provided with a chain e', extending over an i ler e2, secured to a shaft e3, having its bearings in the strips h and b at the grainward end of the platform. Said shaft es is shown in dotted lines in Fig. l. By said chain the con'veyer is operated.

h2 is a cross-bar at the inner end of the platform, secured to the finger-bar B and the strips b and h.

d is an upright secured at its lower end to IOO the cross-bar b2 and the finger-bar B, provided at its upper end with the lug h to receive the upper end of the rod h, by which the buttboard is held in an upright position, the lower end of the rod h being pivoted to the crossbar h2, as shown in Figs. l, 2, and 4.

h2 and h3 are arms secured to the rod z, as shown in Fig. 2, with their other ends pivoted to the butt-board D by bracketst' and t. By said arms `h2 and h3 the butt-board is supported or carried and also operated, as hereinafter described.

The length -of the butt-board D beyond the bracketsz' and t" and the height of the same may be varied according to the size of gavel of grain to be operated on.

j designates a lever pivoted to the bracket f with its free end. Said bracket f is secured to the butt-board near its free or grain- Ward end. The other end of lever lfis provided with a stud f2 to receive the arm I, and to thelower end of said stud is secured the arm Said lever f is supported by the bracket f and the arm I. The armj extends toward the rear, as shown in Fig. l, and is to operate on the stud g3, as hereinafter described. The

' arm I is secured to and carried by the bar J. The stubbleward end of bar J is'pivoted to a block L, secured to the plate a. Said bar may be pivoted to the plate a near t'he iinger-barB or a slight distance to the rear of the finger-bar B, as seen in Figs. 1 and 4. When so placed to the rear, as shown, one or both of thev holes 1J in the arm I should be made somewhat oblong` as shown in Fig. 4, so

'as to give the arm I a slight lateral movement for the purpose hereinafter stated.

The arm I is secured to near the center of bar J. The free end of said bar J extendsa short distance past the pivot of the bell-crank lever P, and is connected to the arm P3 of said lever P by the connecting-rod n. Said lever j P is pivoted to the under side of the plate a a suitable distance from theinner or stubbleward end of the platform, so that the arm P2, extending into the passage-way of the conveyer, will be operated by the same at the proper time, so as to operate the butt-board at the desired time.

V is -a strip of wood secured tothe plate a for the support of the free end of bar J.

g is a bell-crank lever pivoted at its rear to the stud g', secured to the under side-of plate a and located a suitable distance'from the inger-bar B, as shown in Fig. 1, with the arm g2 slightly crooked down, as shown in Fig. 2, and extending to near the arm I and provided with a stud g3 at its free end, projecting upward and into one of the perforations o in the plate ct, so as to withstand the pressure received from the armj.

g4 is a spring secured to the stud g below the lever g and forced against said lever g by a nut Q7. One end of said spring` g4 extends along the arm g2 for four or five inches and is provided with ear laps g to prevent the disengaging from said arm g2. Its other end projects about the same distance beyond the pivot g', with' its end curved upward and in contact with the plate a, and is to prevent the stud g3 from disengaging from the perforation o.` The arm g projects forward and projects from the platform through a slot made in the vertical front a2 of plate a and is provided with an eye g5 on its forward-projecting end. To said eye g5 is secured the shifting-bar 7c by an ordinary bolt or by a hook-bolt la', passing down on the outside of the eye g5, with the hook engaging the eye.

k2 is a strap brought down on the other side of the eye g5, with its hook also engaging the eye g5, so as to prevent the bar 7c from rocking on the lever y. j

The free end of the shifting-bar la extends to the drivers seat and is operated by him. By elevating the free end of the shifting-bar 7c the stud g3 will be disengaged from the perforations o', when it may be adjusted to either one of the perforations o by shifting or drawing the draw-bar 7c. The weight ofthe free end of the draw-bar lc can be so adjustedv as to hold the stud g3 in engagement with the perforations of Without the assistance of the spring g4, above described; but I prefer to also employ the spring g4.

m designates a strip secured to the plate a, as seen in Fig. l, and perforated the same as plate a, and is to strengthen said perforations a. Its front end projects forward to receive the upper end of the pin o. The lower end of said pin is secured to the upper flange of the linger-bar B, as seen in Fig. 3.

The operations may be summarized as follows: The rearward-projecting end P2 of lever P is operated by the conveyer-block C, passing along in the slot A and moving said lever to the position as seen in dotted lines in Fig. l, thereby moving the bar J, to which is secured the arm I, also as seen in dotted lines, thus drawing the stubbleward end of leverf or stud f2 to the rear, and as the projecting armjis in contact with the stud g3 and rigidly secured to the stud f2 on lever f it will cause the lever f to swing to the position as seen in dotted lines in Fig. l. Dur- IIO ing this movement the distance between the pivots f and h of the arms h2 and h3 decreases, thus forcing the arms 71,2 and h3 also out, as seen in dotted lines, thus moving the butt-board D out parallel with the platform, as seen in dotted lines in Fig. 1. As the conveyer moves back it engages the lever P again and moves it back in position, as seen in full lines, thus moving the bar J and arm I and the stud f2 also back in position, as seen in full lines. At this movement the projecting arm 7 comes against the pin o, thus forcing the free end of lever f back, and thereby moving the butt-board back again, as seen in full lines. The distance of movement of the buttboard can be regulated by shifting the stud IZO be moved to a position parallel with the platform, as seen in Fig. 4. For this latter movement the arm I is provided with a slot or slots o (see Fig. 4,) so as to permit a slight lateral movement, so as to avoid an increase in distance between the pivot or bracket f and the pivot h, to which the arms h2 and h3 are sesecured. By curving the bar J slightly and pivoting it near the finger-bar B, as shownin dotted lines in Fig. 4, the arm I can be rigidly secured to the bar J, as in this instance the distance between the pivots f and hwill not increase to an appreciable extent. The lever P springs back far enough into the passageway of the conveyerafter the latter has passed by reason of its elastic connection so that it will be again engaged by the conveyer on its return movement.

Many slight changes can be made in the form of the parts of these devices without a departure from the spirit of or exceeding the scope of my invention. Hence I do not Wish to restrict myself to the exact forms herein shown; but,
